after time you give up on the term vacation ; it becomes "my time off " is busier than when working " . also as you get older the ambition level seems to decrease . I'm saving my $$$$$$$ for a plane ticket west to see the finished DM in person. don't take tooo long I'm not getting any younger. LMAO !!! darn near 73

the title of WORLD leader has gone to world laughing stock .

they don't have any interest in "improving this place" . the ONLY interest they have is :: what's in it for ME ; should I put on pants with bigger pockets to fill. sorry Kids.

Mack most certainly did have twin stick cab overs. H models had with others a twin stick duplex.

thanks for update and results. helps many later on having same situation.

he's NOT slipping! this was his way of testing who is paying attention . after joey retires, He's going to be a teacher in a technical school for mechanical studies. this "slip "was just setting format for teacher to students.

does this unit have a trolley valve on steering column ? brake pedal(treadle valve) floor mounted ?? is the pedal and roller working freely ? this issue sounds to be electrical not mechanical ; don't ask/don't know.

'79 ,should be a brown dash having top panel held by 4 screws ??? do you have yellow parking brake (must have ) ,remove top dash panel to see parking brake valve. seems to me some had an air valve (brake lights on when parking brakes applied. low air small white plastic having one wire which completed circuit ground on firewall as earlier posted .. there may have been an update on brake valve == 1x3/4 white plastic with 2 wires. Another post having the ; wish I could see it in person! actual brake light switch should be on the treadle valve it self. 2 in diameter /2wires

It's not "so old" = it's called past dated . be careful how using the phrase :: so old. LOL

your too young to use excuse "I forgot " that's mine. LOL

I'm old with dementia '' don't have to remember LOL .. It's a post by Rubber duck 006. which I really enjoy reading . interesting to see the "younger generation " keeping tradition alive. THANK YOU Rubber duck for being on BMT.

oh yea now I remember same as the B model had !! what the f--. watched the news regarding the "self driving 18 wheelers . and I think the roads are dangerous now !!! see the mess I-95 is now in CT, will be CLOSED both directions TILL MONDAY . screw CT. let us not go off topic , HI Jojo 😅

so sorry kids 'didn't know this world would come to this. should have realized nov.22.1963

A sensor for steering wheel tilt !!!!! what the heck . so glad I'm over the hill on final trip . If only the younger generation could see what they missed. glad the big rig is so far running properly and can turn the miles in to $$ for you.

in the day I have installed a number of the small bulldog on "rookie rods" . had a few "in stock "in personal inventory and gave them away when moving took place. the plastic models; B model service manuals; and so much more given / thrown away !! where's the crystal ball when you need it ???

once again it's proven " never too old to learn something new!!"... what was always called a fender guide is now known as a "rookie rod "" LOL. have to admit name rookie rod makes a lot of sense. I considered them more of a decoration.

unfortunately , looks as though your back to "square one" . kit you purchased can't be used . steering system isn't anything to modify . based on picture of original pin, the ugly pitted section fits the axle. not major issue IF THEY HAD TO BE REUSED . bushing ends aren't totally a loss. still need correct bushing . entire proper kit.

the super tiny drill bits work well for number of projects. I have many which at a hobby shop or on line you can get the hand held drill bit holders. I have 3, one is a 0-. it goes to 0 lock the smallest bit made. works excellent on hand drilling model front axle king pins also . as Joey stated a torch tip cleaner is even better. variety of micro sizes and stronger. will clean carb ports ; unlike a tiny drill bit which may cut in to a port side wall,

even looking at the Mack logo and stance of the bulldog on service manual says ; Mack is a worker. rugged and bold. once again a regret of " how would I have known to save and keep all those books and manuals I HAD.

THANK YOU for update . question I was asking pertained to rear drive axle (15/16th ? ) nuts . with this unit better than most museum pieces , the axle nuts themselves are tarnished from air gun install. going in for red paint touch up or smaller nut chrome caps ? don't know as if I would want to "slap myself " with thoughts "it's mine "! my luck a slap would wake me up from a amazing dream to find out ; only a dream. not only a major positive reading/ watching this start to finish build ; most important the inspiration YOU have given so many to continue their builds. nothing on this build was in the ordinary. the B-73 / L cab not the usual B-61 etc; roll off bed not standard . perfect color red with no over kill on chrome. can really be pis--d off I can't make Deerfield ; dates are on my calendar for Bethlehem/ Brooklyn/ Macungie

excellent page of reference ; I'm not sure they are all Mack axles although it is in a Mack manual ;; also considering fact I know I didn't work on or remember working on every one.!!. remember the king pin having a threaded top for adjustment (way back ).FA600 series

Oh Gee ;; what next

the later straight pin kits have the larger bearing on bottom between spindle and axle which take the unit weight. reason for tapered lock pin through axle and king pin,

BUT look at picture #1 the original pin VS pin kit they have . the pins are BOTH tapered ; new pin tad shorter which looking at diagram cut away the pins go above bearing . the picture #4 is a pin kit photo supplied by BMT member NOT a correct kit for B model. straight pin having a tapered lock bolt is for much later axle. the tapered king pin should memory be correct is held from spinning in axle by weight on the taper of center section on pin. earlier tapered pin kits had the thicker bushing which required a reamer.

to me that's pure ignorance. having something and not parting with it is one thing; to be cutting/scrapping forever gone parts for a couple $$ is crude. 2-3 K a piece ?? depending on what was cut up, don't think they got that much for whole pile. they could have been not so greedy and took couple hundred for parts and still been a head. so sad.
